摘　　要：为玉米生产上合理利用沼肥提供科学依据,采用直播地膜覆盖栽培试验方法,研究了沼肥不同施用方式对玉米农艺性状及产量的影响。结果表明:1)沼液浸种子24h后,发芽率和成苗率分别达98.73%和99.36%,比对照组高7.06%和14.63%;2)农艺性状,与对照组相比均以处理5最佳,株高达247cm、茎粗达3.3cm,穗位高为120cm,穗长达26.5cm,秃尖仅1.5cm,穗行数为15.5行,百粒重达40g;3)产量表现,处理5达10 100.29kg/hm2,均比对照组和其余处理组高。4)经济效益,处理5的玉米和玉米秸秆的总收入为30 990.7元/hm2,均比对照组和其余处理组高。沼肥不同施用方式均能促进玉米种子发芽率和成活率,促进玉米植株生长发育,以浸种24h,底肥施入沼渣75t/hm2,60%沼液追肥效果最好。For the purpose of providing scientific reference for using biogas manure in the production of corn appropriately,through the experiments of cultivating corns with direct seeding and plastic film mulching,the effect of different ways of treatment on agronomic traits and output of corn was studied.Results：1）The germination rate and seedling rate of seeds soaked in biogas slurry for 24 hours were respectively 98.73% and 99.36%,7.06% and 14.63% higher than the control group;2）Compared with the control group,the agronomic traits of treatment 5was the best,of which the plant height was 247 cm,stem diameter was 3.3cm,ear height was 120 cm,ear length was 26.5cm,ear barren tip was only1.5cm,ear row number was 15,and hundred grain weight was 40g;3）As for the output,the output of treatment 5was 10 100.29kg/hm^2,which was higher than the control group and other treatments;4）As for economic benefits,the total income of corn and maize straw was 30 990.7Yuan/hm^2,which was also higher than the control group and other treatments.All different use methods of biogas manure could promote the germination rate and survival rate of corn seeds,the growth and development of corn plants.Among all these methods,the best method was soaking seeds for 24 hours and putting biogas residue 75t/hm^2 into base fertilizer with 60%topdressing to achieve the best effect.
